Specification of Reissued Letters Patent. 'Reissued Apr. 18, 1922 Original NO. 1,369,681, dated February 22, 1921, Serial No. 382,433, filed May 13, 1920.. Application for reissue filed March 7, 1921. Serial No. 450,482.

To all whom it may concern:

Be it known that I. VALTER N. MCCLEL- LAN, a citizen of the United States, and resi- I which the following is a full, clear, and exact description.

This invention relates to car door operating mechanism and has particular reference to means for controlling the entry and exit of passengers to and from the same, said invention being in the nature of an improvement over the device set forth in Letters Patent of the United States granted to me on the 9th day of March, 1920 No. 1,333,430.

The invention primarily contemplates means for controlling the entry and exit of passengers to and from a car, said means being operable from one control point preferably located within convenient reach of.

the motorman.

Another object in view is to provide an efficient fare collecting means which controls certain passages of the car.

An important feature of the invention resides in the provision of the safety devices for reducing the possibility of accidents to passengers to a minimum.

A still further Ob ect in view resides in the provision of safety doors and means automatically operable thereby for bridging the gap between the station platform and the car. I

A further object in view is to provide automatic signaling means which notifies the motorman that the door passages are clear for the closing of the safety doors. Another feature of the invention is the provision of safety means carried by the door which serves to fend off passen ers attempting to board or leave the car w ile the safety doors are closing.

With the above and other objects in view, some of which will" clearly appear hereafter, reference is made to the following description, claims, and accompanyin drawings which form a part of this application. and in Which,

Figure 1 is a horizontal sectional view through a railway car constructed in accordance with the invention.

Fig. 2 is a vertical longitudinal sectional view. therethrough taken approximately on the line 22 of Fig. 1.

Fig. 3 1s an enlarged fragmentary vertical longitudinal sectional view taken approximately on the line 33 of Fig. 4.

Fig. is a fragmentary horizontal sectional view taken approximately on the line 77 of Fig. 6.

Fig. 8 is a diagrammatic View of the step controlled signaling means.

Fig. 9 is a horizontal sectional view through one of the doors illustrating the fenders arranged thereon.

Fig. 10 is a detail sectional view of the safety covering which may be used in connection with the fenders.

Referring to the drawings by reference characters 10 designates a car provided on its opposite sides with one or more entrance passages 11 and one or more exit passages 12. The opposite ends of the car are provided with cabs 13 for the operator and in which is arranged the controlling means oommonto all of the safety doors.

A sliding safety door 14 is arranged adjacent to each entrance and exit passage and each is Opened and closed by means of a lever 15 pivoted at 16. Each lever 15 is actuated in one direction by compressed air admitted to the cylinder 17 behind the piston head 18 from a supply pipe 19 when a valve 20- is actuated to admit air to the supply pipe from the reservoir 21 which. may be charged in any suitable well known manner. A piston rod 22 is connected by a link 23 to the lever .15 and a coiled compression-spring 24 is disposed between the piston head l8'and the, cylinder head 25 to normally exert a force for effectingtheclosing of the door 14. For holding the door closed or open, a latch 26 is pivoted ad1ame s I viii ed adjacent to the coin box 71 jconiprising rotating iloors in the exit pasthewremoval of 'the coins-- therefrom wlie ever desired; a ,The safety doors a i4 of the car are" respect vely controlledl independently, but controlling means forall) sages, means to prevent the; rotation of said gijdoors "one direction, meansto lock, said rotation in the other direction, coinactuated controlling means for'releasin'g said locking means, and'safety means co- 4 doors on both sides areal-ranged singjjeach -='operatingwith-the rotatin doors to reduce cab; 13 to permit the. operator-to open, all of the safety doors on both; sides when" arriving at a a station in .twhich"" 'the plan forms are disposed at'fbothsides of the car.
